Figure 1From: The effect of column purification on cDNA indirect labelling for microarraysPrinciple of cDNA indirect labelling method, starting form total RNA sample. Total RNA is labeled by reaction of Cy-dyes with amino-allyl dUTP incorporated during the first cDNA strand synthesis (cDNA indirect labeling). The same columns for cDNA purification were used before and after labeling.Back to article page
